Thl Canadian Field- Naturalist 



[Vol. XXXIV. 



They seem to feed almost entirely on meadcw 

 voles and white-footed mice. In twenty disgorged 

 pellets of fur and bones found under roost trees, 1 5 

 contained, each, skulls, c^c. of two M. pennsylvau:- 

 cus, 3, each, one M. penns^lvanica and 2, each, one 

 M. pennsylvanica and one P. leucopus. When one 

 bird is setting the other keeps a plentiful supply of 

 mice; usually a mouse is lying on the edge of thf" 

 nest. 



67. Short-eared Owl, Asio flammeus. Sorre 

 autumns a few are seen, also, on through the winter. 



68. Saw-whet Owl, Cr^pioglaux acadia. Rare 

 only one specimen taken, Novemter 2, 1913. 



69. Screech Owl, Otis asio. Common resident. 



70. Great Horned Owl, Bubo virginianus. 

 Several pair breed near here, laying the last week in 

 February. On April 28, 1914, in climbing to a 

 Great Blue Heron's nest, was surprised to find a 

 young Horned Owl, nearly ready to fly. In a 

 heron's nest a few rods over was another young 

 owl. I tried this bird but it couldn't fly, so I pre- 

 sume the old bird must have moved the one to the 

 second nest — perhaps when they became quarrel- 

 some. Evidently the other nest was appropriated 

 after the herons took possession, as a pair of herons 

 were building a new nest; the other 21 were all 

 occupied. The owls were nearly in the centre of 

 the heronry. I took three specimens in the spring of 

 1918 which I think are a phase of subarcticus. 



71. Snowy Owl, Nydea n^clea. Very seldom 

 seen, more commonly appearing a few miles north. 



72. Yellow-billed Cuckoo, Coccvizu3 ameri- 

 canns. Common; breeds. 



73. Black-billed Cuckoo, Cocc^zus er^ihro- 

 plhalmus. Common; breeds. 



74. Belted Kingfisher, Ceryle alc^on. Has 

 stayed over wmter. 



75. Hairy Woodpecker, Dryobates villosus. T. 

 V. villosus seems to be the common winter form. 



76. Downy Woodpecker, Dryobates pubcscens. 

 Is commoner than the Hairy woodpecker. Several 

 present at all seasons. 



77. Arctic Three-toed Woodpecker, Picoidcs 

 arclicus. W. R. Campbell took a male in 1913 and 

 I a female, Nov. 20, 1918. the only two I have 

 seen. 



78. Yellow-bellied Sapsucker, Sph\)rap>cus 

 varius. Regular migrant. 



79. Pileated Woodpecker, Phocotomus pilc- 

 alus. Two pair nest regularly a few miles south- 

 west of here. One dead beech stub has three 

 nes'.-hclcs about three or four feet apart. The 

 lowest forty-five feet from ground. 



80. Red-headed Woodpecker, Mclancrpcs 

 cr^throccphalus. Not nearly so common as form- 

 erly. Winters over in years the beechnuts are 



plentiful. They seem to nest earlier those years. 



81. Red-bellied Woodpecker, Cenlurus car- 

 olinus. A few pair resident ; but used to be much 

 more common. A nest May 7, 1913, contained two 

 fresh eggs. 



82. Flicker, Colaptes auraius. Very common. 

 An occasional bird staying through the winter. 



83. Whip-poor-will, Anthrosiomos vociferus. 

 Quite regular, never very many. 



84. NiGHTHAWK, Chordeiles virginianus. Al- 

 ways several pairs. Found a nest June 4, 1918, 

 near edge of a small wood. The eggs were laid 

 in the imprint of someone's heel in the earth, only 

 one small leaf under eggs. 



85. Chimney Swift, Chaetura pelagica. They 

 seem to build in silos, granaries, or in barns on the 

 siding as often as in chimneys. 



86. Ruby-throated Hummingbird, Archilo- 

 chus colubris. Breeds. Is quite abundant along the 

 borders of swamps when the spotted jewel-weed 

 (Impaliens biflora) is in bloom. 



87. Kingbird, Tyrannus tyrannus. Common; 

 breeds. 



88. Crested Flycatcher, Myiarchus crinilus. 

 Fairly common; breeds. 



89. Phoebe, Sa^ornis phoebe. Very common; 

 breeds. 



90. Olive-sided Flycatcher, Nuttallornis bar 

 eulis. Only three individuals seen. 



91. Wood Pewee, Myiochanes virens. Com- 

 mon ; breeds. 



92. Yellow-bellied Flycatcher, Empidonax 

 flaviveniris. Rare. One taken May 28, 1919. 



93. Alder Flycatcher, Empidonax Irailli. 

 Two E. i. alnorum taken May 10, 1918. Not 

 more than one or two seen in the sp:'i ig. 



94. Least Flycatcher, Empidonax mininms. 

 Common in migration. Only a very few seem to 

 breed here. 



95. Prairie Horned Lark, Otocoris alpestris. 

 O. a. praticola is a common resident, raising two 

 broods a season. It seems more abundant in winter 

 owing to its being in flocks. Took an albino female 

 June 11. 1917. 



96. Blue Jay, Cyanociila cristata. Resident. 

 They gather in the Cedar swamps in the late fall and 

 eat large quantities of Skunk Cabbage (Symplo- 

 carpus foctidus) seeds. 



97. Crow, Corvus brach})rhynchos. Abundant 

 resident; sometimes rather scarce in winter. Their 

 chief form of recreation seems to be making life 

 miserable for the Horned Owls. Yet they prove an 

 effectual body guard, when the owl is pursued with 

 a gun, always getting him in motion in plenty of 

 time.
